Santander Ordered To Refund Gambling Losses Linked To Offshore Operators

Santander has been ordered to refund gambling losses incurred by a customer who continued making payments to offshore betting operators despite having gambling transaction blocks in place, raising questions about the effectiveness of safeguards offered by UK banks.

The Financial Ombudsman Service (FOS) ruled that the bank must reimburse identifiable net gambling losses incurred between 15 August and 17 September 2025, after the customer informed Santander that he was experiencing a severe gambling addiction.

The complainant, identified only as Mr R, had received approximately £25,000 following the sale of his house in July 2025. He subsequently spent much of the money gambling through offshore operators, with transactions continuing despite restrictions intended to prevent gambling-related payments.

The decision highlights the difficulties financial institutions face when attempting to block transactions involving gambling businesses operating outside Britain's licensed market.

Ombudsman Orders Refund And Compensation

The dispute centred on Santander's responsibilities after Mr R contacted the bank on 15 August 2025 to disclose his gambling problem and explain that his behaviour was becoming increasingly difficult to control.

Although gambling payment blocks had already been established on his account, Mr R continued transferring money to offshore gambling platforms. Santander subsequently introduced an international gambling block, but the customer reported that he was still able to make gambling transactions.

The Ombudsman concluded that Santander should reimburse identifiable gambling losses incurred between 15 August and 17 September 2025, deducting any winnings received during that period.

The bank was also instructed to pay 8% interest on the relevant gambling transactions and provide £500 in compensation for the distress and inconvenience caused.

However, the decision did not require Santander to reimburse approximately £16,000 lost before 15 August. The Ombudsman found insufficient grounds to hold the bank responsible for those earlier transactions because it had not yet been informed of the severity of the customer's gambling problem.

Santander disputed its liability during the complaint process, arguing that Mr R had independently chosen to gamble with offshore operators and remained responsible for those transactions.

The Ombudsman's decision nevertheless distinguished between the period before the customer disclosed his vulnerability and the subsequent transactions, when the bank had been made aware of his circumstances.

Offshore Gambling Exposes Limitations Of Banking Safeguards

The case has drawn attention to the limitations of gambling payment blocks, which are offered by major UK banks to help customers restrict access to betting and gaming services.

These safeguards generally work by identifying gambling-related transactions through merchant classifications used by payment networks. However, payments involving offshore operators or intermediaries may not always be recognised as gambling transactions, potentially allowing customers to bypass existing restrictions.

In Mr R's case, the disputed transactions involved offshore gambling businesses rather than operators licensed by the UK Gambling Commission.

The continued payments, including those made after Santander introduced additional restrictions, demonstrate the challenges banks can encounter when attempting to identify and prevent transactions connected to gambling services operating outside the domestic regulatory framework.

The issue has become increasingly relevant as UK authorities intensify their efforts to disrupt illegal gambling businesses, particularly by targeting the payment systems and financial arrangements supporting unlicensed operators.

Recent Gambling Commission research has also highlighted concerns about the relationship between gambling-related harm and participation in offshore gambling markets, with higher-risk gamblers identified as particularly likely to access operators outside the licensed system.

Gambling Blocks Remain An Important Protection Tool

Gambling payment blocks have become an established feature of UK banking services since digital banks Starling and Monzo introduced app-based controls in 2018.

Santander introduced its own gambling block in 2019, joining other financial institutions in offering customers the ability to restrict payments to gambling merchants.

The development of these services has been supported by the Gambling Commission and GambleAware, with research conducted alongside the University of Bristol examining how banking safeguards could help reduce gambling-related harm.

However, researchers have previously raised concerns about inconsistencies between the protections offered by different banks, particularly where customers can deactivate restrictions without a meaningful cooling-off period.

Calls for standardised safeguards, including a minimum 48-hour delay before gambling blocks can be removed, have not resulted in a universal requirement imposed by the Financial Conduct Authority (FCA).

Although the FCA has recognised gambling payment blocks as a useful consumer protection measure, banks retain considerable discretion over how their individual services operate.

The Santander ruling illustrates the importance of those safeguards functioning effectively once a financial institution becomes aware that a customer may be vulnerable to gambling-related harm.

It also reinforces the wider challenges associated with offshore gambling, where operators and payment arrangements outside the UK regulatory system can complicate efforts to protect consumers.

For banks and regulators, the case highlights the need for effective identification of gambling transactions, particularly when customers have explicitly requested restrictions or disclosed circumstances requiring additional protection.
